That’s a pretty big could. Johnson won in ‘10 with 75-25; John Lewis in the neighboring 5th won with 74-26, and David Scott won with 69-31.
How do you figure Vaughn (or any R nominee) needs anything below 35%? And that’s only if Johnson and McKinney split the remaining vote equally.
What was the lowest percentage to win a Congressional seat?
Off the top of my head NM-2 1980: Joe Skeen 38%, David King 34%, Dorothy Runnels 28%.
(I recall the race — had to look up the numbers)
I dunno, it could be that kind of ABO year.
